Frequently Asked Questions
Q: What is the SY75157 roll pin and where is it used on a pallet jack?
A: The SY75157 is a spring-loaded cylindrical pin that secures pivot joints, linkage arms, and handle brackets on manual pallet jacks. It holds moving components in alignment and prevents lateral movement or separation under load.
Q: What are the dimensions and material of the SY75157 roll pin?
A: The SY75157 roll pin is 5/16 inch diameter by 1.5 inches long, manufactured from spring steel with a zinc plated finish. The hollow tubular design allows it to compress slightly when installed, creating a spring-loaded grip that locks the pin in place without separate fasteners.
Q: What pallet jack brands use the SY75157 roll pin?
A: The SY75157 is compatible with manual pallet jacks from Crown, Yale, Raymond, and Toyota. Verify the exact pin diameter and length for your equipment model, as different models use different pin sizes.
Q: When should the SY75157 roll pin be replaced?
A: Replace the roll pin if it falls out, becomes bent or deformed, or loses tension. If linkage arms rattle or move loosely, the pin may have lost its spring tension and should be replaced. Inspect all roll pins during regular maintenance, especially if the jack experiences frequent use.
Q: How long does the SY75157 roll pin typically last?
A: Under normal warehouse use, a roll pin lasts 5 to 7 years before the spring tension degrades. In high-cycle operations or outdoor conditions with wet or salty air, replacement may be needed every 2 to 3 years due to corrosion or spring fatigue.
